APPARATUS FOR MIXING LIQUIDS WITH GASES.

SPECIFICATION forming part of Letters Patent No. 591,831, dated OctoberlQ, 1897. V

Application filed June 22, l 8 7.

T 0 all 1071,0771, it may concern.-

Beit known that I, ROBERT Gr. FERGUSON, a citizen of the United States, and a resident of Lakewood, in the county of Ocean and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Miniing Liquids with Gases, of which the following is a specification.

This invention relates to an apparatus for charging liquids with gases, and more particularly designed for producing effervescent or Nauheim baths, though the product of the apparatus may obviously be used for other purposes. I propose to employ a portable cylinder subdivided in a peculiar manner and adapted to be charged with the water, gas, and chemicals necessary to form the effervescent liquid. The charged cylinder is delivered to the consumer, who connects it to the water-main and uses it until empty, when it is exchanged for a charged cylinder; In this way the preparation of efiervescent baths is greatly facilitated, and such baths are put within the reach of the occupants of hotels and dwelling-houses generally.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of my improved apparatus for mixing liquids with gases. Fig. 2 is a plan; Fig. 3, a vertical cross-section on line 3 3, Fig. 1; Fig. 4, a detail of the joint between the gas-pipe (0 and the injector-pipe b, and Fig. 5 a detail of the gas-regulating valve to The letter represents the body of a cylindrical vessel or fountain divided into three compartments ct a a by means of two trans verse partitions a a Of these the partition cu is foraminated to constitute a strainer, while the partition a is perforated to permit communication between the compartments a a This communication is, however, normally interrupted by a check-valve a, closing by gravity upon a seat that is formed upon a short tube 0. which projects from the perforated partition a into the compartment (0 The compartment (4* is, by a hand-hole a adapted to be charged with the salts or other chemicals necessary to form three, more or less, baths. It is also, by connection a, controlled by valve C610, adapted to be coupled to the water-main. The water charged with the Serial No, 641,750. (No model.)

salt within the compartment a passes through the strainer a into the delivery-compartment a, and from thence, by connections a, controlled by valve a, into the outer or fixed tube 1) of an injector, to be there mixed with the gas in manner hereinafter described.

The compartment a is provided with a connection 61, for charging it with gas, and with a pressure-gage a. It is also provided with a gas-outlet pipe e which is bent so that its mouth is placed within a short distance from the roof of the compartment, while its lower end connects with an opening of the cylinderhead. Here the pipe (615 is,-by connection a having gas-cock a", connected to a T-coupling a, containiuga gas-regulating needlevalve to, Fig. 5. The T-couplin g a communicates with the gas-pipe a that embraces and communicates with the inner longitudinally-adjustable tube 1) of the injector, the nozzle of which discharges into the fixed tube 1), Fig. 3.

The pipe a projects a short distance beyond tube 19, and is thereprovided with a hose-coupling cfiflhaving cock (L so that the gas may be delivered to the injector from an independent gas source, in lieuof being 'delivered thereto by the compartment (1 In order to permit the relative proportion between gas and liquid to be regulated, the tube 6' is made longitudinally adjustable within tube b, so as to thereby adjust the size of the liquid-discharge passage formed within tube 1), around the nozzle of tube 1). To effect this adjustment, I make the tube b revoluble and suspend it within a nut 5 supported on tube 1). At its upper end the duct of tube 19 terminates in an annular groove 5 Fig. 4, that communicates permanently with the bore oftube a By revolving the tube 1) it will thus be raised or lowered to regulate the discharge, the slight adjustment required being permitted by the natural resiliency of pipe a The water charged with gas flows from tube 1) into a perforated thimble b and thence through pipe b containing a number of fixed perforated superposed plates 11 into the delivery-tube If, that may be provided with a rose 19*, and delivers its charge to a bath-tub or other receptacle, ready for use. If the gas pipe 19 of the injector.

has been used up to such an extent that the gas-pressure within the compartment a has fallen below the water-pressure in compartment a the valve to will open and water will flow into the compartment a to displace the gas and drive it out through the pipes at a. Owing to the elevated position of the mouth of tube (1. this water will, however, be prevented from entering such tube, and in this way practically all the gas in compartment a can be used up. After all the gashas thus been ejected the water may be drawn out of compartment a by means of a drain-pipe (0 that connects, preferably, with the discharge- The compartment a being thus relieved of its gas and freed from water, is ready to be freshly charged with gas, that may be supplied from a suitable source by connection a What I claim 'is 1. In a mixing apparatus, a cylinder having a perforated partition that divides it intoa gas and'a Water compartment, and a valve that controls the opening in said partition, means the in jector-tubes, substantially as specified.

for connecting the cylinder to the water-main and controlling the flow of water into the cylinder, a mixing-chamber and valve-controlled passages leading from the Water and gas compartments to the mixing-chamber, substan- I pipes connecting two of said compartments tially as specified.

2. Inamixing apparatus,acylinder having one of said compartments, substantially as a strainer and a partition that divides the cylinder into a gas-compartment, and a watercompartment, means for connecting the cylinder to the water-main, a mixing-chamber and valve-controlled passages from the water and gas compartments to the mixing-chamber, substantially as specified.

3. In a mixing apparatus, acylinder having a strainer, a perforated partition and a valve that controls the opening in said partition, means for connecting the cylinder to the water-main and controlling the flow of water into the cylinder, a mixing-chamber and valve-controlled passages leading from the water and gas compartments to the mixingchamber, substantially as specified.

4. In a mixing apparatus, a cylinder containinga delivery-chamber, a chamber to contain salt, and a gas-chamber, the said chambers being separated by a strainer, and a partition having an opening therethrough controlled by a valve, combined with means for connecting the salt-chamber to the watermain, means for regulating the flow from the delivery-chamber, and means for mingling the gas and the Water.

5. In a mixing apparatus, a cylinder having a transverse strainer, and a valve-controlled transverse partition, and which is by the strainer and partition divided into three compartments, combined with an injector having a water and a gas tube, and with pipes that connect two of the cylinder-compartments with 6. In a mixing apparatus, a cylinder provided with a transverse strainer, and a valvecontrolled perforated partition to form three compartments, combined with an injector,

with the injector, and with a drain entering specified.
